tools arch x86: Sync asm/cpufeatures.h with the kernel sources
To pick up the changes from:
b4dd4f6e3648 ("x86/vmware: Add a header file for hypercall definitions")
f36cf386e3fe ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS")
be261ffce6f1 ("x86: Remove X86_FEATURE_MFENCE_RDTSC")
018ebca8bd70 ("x86/cpufeatures: Enable a new AVX512 CPU feature")
These don't cause any changes in tooling, just silences this perf build
warning:
Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'
diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h
To clarify, updating those files cause these bits of tools/perf to rebuild:
CC /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
CC /tmp/build/perf/bench/mem-memset-x86-64-asm.o
INSTALL GTK UI
LD /tmp/build/perf/bench/perf-in.o
Those use just:
$ grep FEATURE tools/arch/x86/lib/mem*.S
tools/arch/x86/lib/memcpy_64.S: ALTERNATIVE_2 "jmp memcpy_orig", "", X86_FEATURE_REP_GOOD, \
tools/arch/x86/lib/memcpy_64.S: "jmp memcpy_erms", X86_FEATURE_ERMS
tools/arch/x86/lib/memset_64.S: ALTERNATIVE_2 "jmp memset_orig", "", X86_FEATURE_REP_GOOD, \
tools/arch/x86/lib/memset_64.S: "jmp memset_erms", X86_FEATURE_ERMS
$
I.e. none of the feature defines added/removed by the patches above.
